Some founders ship fast.
You're building something
that holds.

Fractional technical leadership for East African founders building AI-powered products embedded with you for the six months of architecture decisions that are expensive to reverse. AI strategy first. Stack second.

Who We Are

A deliberately small technical practice.

Kosentia is a boutique advisory built around a single principle: the person making your architecture decisions should be the person in the room with you. No account layer, no handoff to a junior team. Two clients per quarter because embedded technical partnership cannot be spread thin.

Most technical playbooks are written for stable infrastructure and mature capital markets. They break in the markets where the next billion users actually are. Our depth is East Africa multi-rail payments, informal-sector data, fragmented health records the conditions that are becoming the global norm, not the exception. Architecture that holds here travels.

"We build what your market tests. Not what your deck shows."

What you get when you partner with us
01

AI strategy first, stack second

The AI decision comes before a tool is chosen. Starting with the stack and fitting AI in is how production systems fail we've seen it, and we don't repeat it.

02

Every decision documented and owned by you

You leave with the full picture code, architecture decisions, and the reasoning behind them so any engineer can understand it and any investor can audit it.

03

Calibrated to your stage, not a generic playbook

What works at pre-PMF breaks at Series A. We know the difference and we move with you not behind a framework designed for someone else's company.

04

Built inside it not briefed on it

East African market conditions are not context. They are the foundation. M-PESA rails, informal sector data, fragmented health records we have built inside all of it.

05

Built to outlast us

The system is designed to outlast the engagement. You leave with a technical foundation that any engineer can run, extend, and own without depending on us to explain what was built.

How We Work

From AI strategy
to production systems.

Every engagement begins with AI architecture not tools, not platforms, not frameworks. The stack is chosen after. This is the decision most advisors skip. It is the one that determines everything downstream.

Engagement Models

Project-Based

4–6 months · Discovery → Build → Optimise

For founders who need to move from idea to a validated, production-ready system. We scope a specific outcome and own its delivery end to end.

  • Technical assessment
  • Architecture design and validation
  • Hands-on implementation
  • Documented handover
Available add-ons
+ Branding & design systems
+ Compliance & legal documentation
Investor-readiness session included with every engagement. A direct, unscripted conversation with an active early-stage investor. We don't name them publicly they take these as a favour to the practice, not as a service but they invest at the stage you're raising for. No pitch, no deck. Just the technical questions a diligence process will actually ask, before you're in the room for real.

Who We Serve

For founders building AI
products that must work
not just demo well.

We work with pre-PMF to pre-Series A founders in Kenya and East Africa making architecture bets they cannot fully validate alone in markets where the patterns imported from abroad do not hold, and where getting those bets wrong is more expensive, not less.

Capacity
We take 2 clients per quarter.
Not a constraint a commitment.

Two clients means one thing: if we are working with you, you have our full attention not a fraction of it. We are in the decision alongside you, accountable for the outcome, embedded in the product. That is what two clients per quarter makes possible.

FAQ

Questions
we get asked.

Honest answers. If yours isn't here ask directly.

Genuine embedded partnership the kind where we're making decisions alongside you and answerable for the consequences can't be spread across ten clients. Two is the number at which the work holds the standard we've set. It's a commitment to your success, not a capacity limitation.
Pre-revenue is often when architecture decisions matter most they're the hardest to reverse once a product is live. Whether it's the right time depends on whether you're making decisions now that will be expensive to undo later. If you are, that's the moment to talk.
A 30-minute conversation about what you're building and where you are. There's no bar to clear before reaching out we want to hear from you. From there, we both decide if working together makes sense. We evaluate fit as carefully as you do. No pressure, no pitch.
Yes and this is often where the partnership produces the most value. You understand your market, your users, and your vision. We translate that into technical decisions that hold up when tested. That combination is what makes the work worth doing.
You do fully. Code, architecture decisions, and documentation are yours. Every significant decision is recorded in a decision log so any engineer can understand what was built, why, and what was considered. The system is built to outlast us.
Included with every engagement a direct, unscripted conversation with an active early-stage investor. We don't name them publicly they take these as a favour to the practice, not as a service but they invest at the stage you're raising for. No pitch, no deck. Just the technical questions a diligence process will actually ask, before you're in the room for real.
Most freelancers build what you specify. Most consultancies leave when the project ends. We do neither. We are in the decision not just the execution which means we push back when the spec is wrong, and we document every architectural choice so the reasoning outlasts the engagement. You end up with a system any engineer can extend, audit, and own. That is a different kind of practice.

you're building.

No criteria to meet before you reach out. If you are a founder making architecture decisions you cannot fully validate alone this is the right conversation to start. We will figure out together whether it makes sense to work together.
